For Filipino moms and dads, in this day and age, do you still practice the use of "po" and "opo" and teach your kids to do the same?

We haven't tried it since my kids weren't taught to speak in Filipino yet. But eventually, I really plan to expose them to the Filipino language so when they go to school, they won't have a hard time communicating with their peers. I would definitely teach them the use of 'po' and 'opo' especially when talking to older people.
